    Which Graphics Card do you have? Did you install driver of Graphics card?
    Execute this
    Code:
    lspci | grep VGA
    cat /etc/X11/xorg.conf | grep Driver
    Post output here.
    It is amazing what you can accomplish if you do not care who gets the credit.

    Driver is correct. Does /var/log/Xorg.0.log list any error?
    Post the kernel line of /boot/grub/grub.conf file.
    Code:
    less /boot/grub/grub.conf | grep kernel

    No i usually log-in command prompt and then i used to give startx.

    this is the line in grub.conf
    Code:
    kernel /vmlinuz-2.6.9-42.EL ro root=LABEL=/ rhgb quiet

    Even if you execute startx command, Xorg.0.log file logs all messages. You should look into that file. Kernel line and Driver in xorg.conf are correct.
    Try appending kernel line with vga=773.
    Code:
    kernel /vmlinuz-2.6.9-42.EL ro root=LABEL=/ rhgb quiet vga=773
